Abstract

Aim: In spite of well-known health promoting benefits of exercise, due to increased ventilation during exercise and higher concentrations of pollutants while the air quality is unhealthy there is increasing concern about exercising in polluted air. Therefore, the present study aimed to compare the effect of air pollutants on salivary malondialdehyde (MDA) and total antioxidant capacity (TAC) response to a bout of exercise in indoor and outdoor environment in male adolescent futsal players. Methods: Twelve male adolescent futsal players completed the Bangsbo protocol in two environments (indoor vs. outdoor) at two air quality conditions (Air Quality Index 50-100 = Healthy, and 100 to 150 = Unhealthy). Salivary samples were collected before and immediately after performing the protocol in each condition. MDA and TAC were assessed using specified kits (Zelbio-Germany). Data were analyzed using analysis of covariance test (p < 0.05). Results: Finding confirmed that in comparison with healthy air condition, the basic and post exercise levels of salivary MDA were higher in unhealthy air condition - both at indoor and outdoor (p < 0.05). Moreover, in healthy air condition in response to exercise protocol changes of salivary TAC in –both indoor and outdoor- was incremental (P>0.05) but in unhealthy air condition -both indoor and outdoor- its changes was decremented (p < 0.05). Conclusion: Findings of present study confirms that unhealthy air condition has negative effect on salivary MDA and TAC response to exercise. Moreover, it seems that relocating the exercise to an indoor environment in unhealthy air condition does not reduce the negative effects of unhealthy air on the salivary MDA and TAC response, and there seems to be need for evidence-base recommendation to reduce the negative effect of unhealthy air on oxidant-antioxidant system response to exercising in unhealthy air condition.
